I don't think you can set the output if you're using the arithmetic combinator as the prototype. That already has a behaviour associated with it: it does arithmetic, according to the settings in its control behaviour. If you want to output signals of your choice you would need to use a constant comb...

Productivity modules change ratios even if you have the exact same modules. Say you have a 1:1 ratio where machine A is feeding machine B. If you add 10% speed to both nothing changes as they still take the same relative time to craft, but if you add 10% productivity to both then now machine A outpu...

Is there any way to ONLY prevent the circular-feedback activity at this location, but to leave all other behavior intact? I.e., a city-block with a reduced-priority LTN-requestor intake trainstop, that can generally receive LTN-routed shipments of materials from any valid provider elsewhere; AND an...

Health check doesn't exist every tick, it only gets used if the robot is damaged or repaired somehow, and those are reactive events - they only happen if something triggers it, or it happens to be on screen to draw the health bar, so the vast majority of the time a robot is out it's health is never...

Ok, thank you for the help. If i will delete all red and green wires, i will also have all the Content in the logistic network? I think about it like Wireless Lan and Wired Lan :) The circuit network and logistics network are entirely separate; roboports connect to each other wirelessly as long as ...

The roboport just outputs the contents of the entire logistics network to the circuit network: everything stored in any reachable red/yellow/purple/green chest. There is no distinction between the red and green wires here, just like every other building: the signal it's outputting is output onto *an...

OP might want to just look at Train Supply Manager rather than (or in addition to) LTN. The basic use case for TSM is exactly what they described: fill up a bunch of trains with bulk outputs that then wait at a "depot" until they're needed by a requester station. LTN is designed around tra...

It doesn't check this at all. If you want to have separate disconnected networks then you need to set the network IDs on all the stops so that they are considered different networks by LTN.

I'm sure other people have thought of smarter systems though

If you have a gate to "summon" the train, you could run a wire around the entire base to carry the "summon" signal everywhere, and then have a couple of combinators at each train stop to check if the global summon signal is set *and not the local summon signal* - i.e. the train ...

I guess you also cant have specific limits for specific items. Can i atleast blacklist some items? Or whitelist. You can't have per-item limits in LTN itself; you can do things with combinators as boran_blok suggests but depending how you implement it it may or may not have undesirable edge cases. ...

I have a "universal" provider (from your thread), ive set min items to 10. This means that LTN will not send a train to this provider unless the provider has at least 10 items available pick up. I have created a normal requester station with min item 200 and min stack 20. This means that ...

I think many people building megabases are either just picking some arbitrary SPM as their "goal" to aim towards and seeing if they can make a factory that reaches that, or are just seeing how high they can get to before they either lose interest in that savegame, or lose the ability to ru...

Being held at a different point is still useful even if it places the blueprint at exactly the same location in the world :) For example my train-supplied defence wall blueprint is chunk aligned, much wider than it is tall, and has a station in the middle of the blueprint; being able to set the blue...

Accumulators don't charge from each other. The accumulator-as-resistor only works to supply actual energy consumers.

The complicated setups to take out 1 each time and only let exactly 40 cycle around aren't strictly necessary; you can just make a looping system with no logic like boran_blok shows and as long as it prioritises keeping kovarex going over outputting 235 for use it will eventually fill the loop and o...

FYI https://mods.factorio.com/mod/CursorEnhancements implements this (and the other direction when you run out), as well as some other nice features.

Yeah, pipes and tanks behave like they're separate containers and the flow rate from one to the next depends on the difference in fluid level. The more of these in a row there are, the greater the difference in fluid level between the first and last will be as a result, and once it gets long enough ...

You're pushing the steam through way too many tanks and pipes. There's only enough steam making it through all your fluidboxes to power a small proportion of your steam turbines; the rest are empty. Look at the fill levels of your steam tanks for example: the ones nearest the heat exchangers are nea...
